Specification of Letters-Patent. I Application filed larch 19, 1908. Serial No. 422,081.

Be it known that I, WILLIAM H. MUzzr, a citizen of. the United States, residingat Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Comblnation Type-Writing and Adding" Machines, of which I declare the followingt'o be a full, clear, and exact'descripti on.

This invention relates to improvements in combined typewritingand adding machines.

The principal object of the inventionis to provide typewritin and adding mechanisms, soconn'ecte'dt at the proper additions are enforced according to amounts printed by the typewriter.

With this and incidentalobjects in view,

' the invention consists in certain novel feaated position, the parts in a Fig.

tures of constructionand combination of parts, the essential elements of' which' are set forth inappemled claims and a preferred form 90f embodiment of which is hereinafter specifically described with reference to the drawings which accompany, and form part of this specification.

Of said-drawings: Figure 1 represents afront elevation of the tylpewritingand adding machines, with the p tform upon which them'achinos are mounted in section, and showing the connections embodying the present invention. Fig. 2 represents a transverse section taken on the line 2-2 of- Fig. 1, showing the auxiliary 'key board in:

section. 'Fig. 3 represents a transverse section through the typewriter on" line 3-3 of Fig. 1'. Fig.4 represents a detail section of the key locking frame of the typewriter and its cooperating parts in a artially 0 eralso shbwing ih dotted lines completely operated position. 5 represents a detail perspectivekof the typewriter space bar aiid connection. F ig;

o represents a horizontal section throu h the 'latch'controlling mechanism; and Fig. 7 represents a horizontal sectionthrough arow of the auxiliary keys of the adding machine.

There has been shown in the dawe s, is

-'j one'illustration of the invention, a standard tions, such that the keys of the addin chine, which are normally locked, wil

make of a Remington typewriter and a Burroughs addingmachine with connecma- 1 k d b h f h (il co e=un oc e yt eoperation o t e t keg s of the-typewriter, and thelatter g1 as any other well known type may be emupper'r ow of key .ten' digit keys,

keys

I will then become locked and will only be released when corresponding keys and the operating handle of the adding machine have been operated. An auxlllary .key

board-is pivotally mounted upon the adding machine and is so arranged that, when in place,.the keys thereof will register withthe corresponding keys of the permanent key hoard mani ulation of the former keys will actuate t e'latter. The connections and additions to the several machines may be disconnected and readily removed, so that each machine may be used independently of the other."

, ypifwm'ten-As previously described, the style of machine shown in the drawings is that of the Remington type, butit is to be. distinctly understood thatthis inventionis not to be limited 'to this style of machine,

ployed with equal facility. Y

' The keyboard comprises four rows of keys 1 and a space bar 2, all Of which are pivotally mounted attheir rear ends upon a transverse rod 3, and'held' in their normal elevated positionby 'leaf'springs 4 secured to a bar 5, the rod 3 and bar 5 bein suitably supported by the side frames6 o the machine. (The key levers 1 are connected to their respective type" bars '7 by links 8, 9 and 10,]the said ty mounted upon short stub shafts 11 and arranged to-be-swung into contact with a platen 12 u on the operationf key levers 1, -as is wel understood in-vthe art. The" lovers 1 is composed of the of which nine' are connected to levers 13 by links 14., the said-leversbeing pivotally mounted at their rear ends upon atransverse rod 15, which issuitably securedwithin a base 16, upon.

which the .typewriting and adding machines are mounted. Each of the levers 13 is pro-' videdat its forward end with a link 17, the 100 lower end of which is connected to a lever 18 mounted on a transverse shaft 19. The forward end of each lever 18 is rovided with a spring pressed awl 20, whic 1 is limited in its movements age a gear wheel 21' and turn said wheel orward one tooth. This wheel 21 isffast to a disk 23, which is journaled upon a transverse shaft :24,- and is formed with a notch 25 in its no Patented Jan. 2, 1912.

:of the adding machine, so that a pe bars being pivotally I (from 1 to 9) I l y stop pin 21, and is arranged, when operated, to en -naled upon the forward one of a series of transverse shafts 22 and are normally held up at their forward ends by coil springs 30, which connect them to the frame of the machine.

- It will be seen from the above that when one of the disks 23 is rotated by its pawl 20,

. the links the rod 26 is forced out of the notch 25 and 28 thus drawn down. This action of the links also draws down the forward ends of the levers 29, so that looking lugs 3S projecting upward therefrom are moved from behind a cross bar 39 of the locking frame 31,, and thus permits the frame 31 to be drawn rearward by its spring .36 into the position shown in Fig. at in which its lugs 35 will contact with the hook ends of the latches 34. The levers 29 arev also provided with lugs 10, each normally supporting a pivoted latch 41. WVhen the levers 29 are depressed, as above described, the lugs 40 permit the latches 41 to descend and rest on the cross bar 39 of the frame 31, so that when this frame is subsequently released from the latches 34 by the operation of the space bar above described, the frame will spring rearward under the levers 13, and the latches 41 will descend in front of the bar 39 and thus lock the frame 31in position to intercept any movement on the part of levers 13. The resultof this operation is to look all the digit keys of the typewriter. Should any particular key of the typewriter be operated a plurality of times in printing a certain numeral, its proper lever 18 will be operated corres )ondingly and its proper disk 23 fed forwart a corresponding number of teeth. It will be understood that as long as any one of the disks 23 is displaced from its normal position, shown in Fig. 4, the links 28 will be held down and the levers 29 held in their depressed position with the latches 41 in front of the bar 39, which will prevent the frame 31 being operated. It thus becomes necessary to return any of the displaced disks '23 to their normal positions in order to unlock the di it keys of the typewriter. This backwar movement of the disks is effected 'by connections with the adding machine as follows: Each of the transverse shafts 22, which is suitablv supported .in the base of the machine, is provided with a pendent arm 42, provided at its lower end with a pin 43, Each of these pins projects into an incline slot 4.4 formed in the rear end of a lever 45, said levers being all fulcruined on the shaft 19 5 and each ofthe same provided at its forward respective gear whee wheel one tooth eac end with a spring pressed pawl 46,'which is limited in its movement by a pin 47. The

disks 23 from gear wheels 2], and turn said disks in a reverse direction from that in which they are turned'by pawls 20.- Thc pawls 20 and 46 are substantially identical and each of the same normally occupies a position out of the nth of the teeth of its Each disk 23 is also provided with a stop lug 48 which contacts with a transverse shaft 49, upon which are mounted spring pressed restraining pawls 50 which engage the teeth of the gear wheels to prevent overthrow of the same. one ofthe disks 23 has been moved forward a certain number of teeth by the pawl 20, it is returned with a step by step movement by the pawl 46 which rotates it in the opposite direction, this pawl acting to turn the time its corresponding shaft 22 is rocked. 1

Connected to the side arms 32 of the space bar 2 (Figs. 3 and 5), by slot and pin connections 32 and 32* respectivel are link bars 33, the lower ends of whic are connected to locking )awls 34 pivoted at their rear ends upon stu shafts 27. The forward hook ends of these pawls engage downward extensions 35 of the locking rame 31 and After hold said frame in a retracted position.

Upon depressing the space bar 2, the pins 32 will contact with the lower ends of the slots 32 and lower the links 33, which will rock the pawls 34 out of engagement with the extensions 35, and allow springs 36 to draw theframe 31 under the levers 13 and thereby lock said levers and the digitkeys 1 from operation. The frame 31 is limited in its rearward movement by pins 37 projecting form 16.

It will br seen from the above description that the .digit keys of the typewriter are locked by the movement of the space bar.

Adding machine.-The Burroughs machine shown in the drawing is well known upon the marketgand needs nodetail de script-ion, it being sufficient to state that it comprises a plurality of keys 50, ,which determine the amounts that are to be regis tered and recorded upon the machine by the operation'of the handle 51.

from the side walls of the plat- Qbase. of the machine. each rod 60 is fastened writer are operated, their series Eff-transverse rods ,56, one for each horizontal row of keys 53, is loosely mounted in the side walls 'key board 52 (Figs.

extending laterally from the keys 53, contract with the hp nsides of the'fingers 57,

and therebyi ro j the shafts '56 when said i keys aredepressed. Upon the extreme left hand end 0 each rod 56 (Fig. 7), is a'rcar- I wardly' extending finger 59, similar" to the e'rsbZ-ywhich plays in the upper forked en of a vertical rod 60, the latter being suitably guided by a block 61 secured to the The lower end of to a rearwardly extending arm 62 secured to the right hand end of one of the-transverse rods 22, which extends throughto the typewriter mechanism.

struction, that upon the operation of any ,manipulative device 53 in any row, its corresponding rod2'2 willberocked through means of the pin 58, fingers 67., '59 rod 60and arm 62; The digit. key of the typewriter, bearing the Zero character, does not operate a lever 18, because the style of adding ma- ,chine showndoes not employ zero keys, it

being understood that if the type of machine used in connection with the typewriter, employs .-a zero key or keys, the zero key of the typewriterwould then actuate a lever similarly to the remaining digit keys.

It will be seen from the above that, when any number of amount keys of the typedisks 23 are correspondingly adjusted and the frame31 released when the space baris finally oper ated. As the keys of the adding machine are operated, the disk; 23 are returned to their normalpositions, which operation releases the levers 29, and the same passing upward, raise the latches 4.1 .from in front of the bar 39' and leave the frame 31 free to be forced forward again into its normal position, shown in Fig. 3.' This operation of the frame is accomplished, through the medium of the shaft 19upon which it is rigidly mounted, by means of an arm 65, which is rigidly connected to the opposite end of said shaft and is provided. with-a pin 66? with which the operating handle 51 of the adding machine contacts just as the handle reaches the'end of its forward movement. This operation rocks the shaft 19 sufficiently to more the frame 31 so far back that the lugs 33 again pass up to the rear of the bar 39 and lock the frame in position as shown in Fig.3. It will be thus seen that, after the typewriter has been operated to print .certainnumerals and the space bar then actuated, the typewriter cannot be again op '65 eratedfor printing numerals until the add .with arms 71 ponding machine has been operated to add the numerals corresponding to those-written on the typewriter. .The operation of the adding machine must include, not only the pressing ofthe keys, "the handle before the typewriter is returned to a position in which mechanism under the the typewriter is again free for printing of numerals. When all the parts are in normal position with the lugs 48 of the disks 23 in contact. with the transverse shaft 49, the manipulative devices of the adding machine will be locked from operation, because the disks 23 which lative devices have reached the limit'of their reverse movements.

are actuated by said manipu- As it is sometimes desirable to throw out the lockingmechanism so that the typewriter may be employed for printin numerals, such as-dates, which are not to e added pen the adding machine, I provide means for It will be seen from, the "above con-- accomplishin this result. This means comprises a sha t 7 1 suitably mounted in the ['casin and provided at its outer end with a thum knob 72 by means (of which it may be adjusted and, having alug 73, which, when'the shaft is turned, contacts with one ofthe lugs 35 of the frame 31, and thus prevents the framespringin'g int-o locking position even when the amount keys and space 'barare operated. Shaft 71 is. provlded tails of the pawls' 20 and move the latter out .of operative position when the shaft is rotated. It will, of course, be understood that ordinarily the typewriter can be used with the lettered keys and space bar without any lockingtaking place, and that is only when the numeral keys are the machine becomes locked u the corresmachine.

If the manipulative devices 53, of the rows, corresponding to the previously actuated digit keys ,of the typewriter are not operated! will be understood that the ban 1e 51 cannot be completely operated,

because the frame 31 is locked against return by the pawls 41. The handle can be released from this position by tilting the platform 16 manually or in any desired .manner and trippingthe pawls 41, so that .the handle can complete its stroke. It is, of course, to be understood that upon the operation of the manipulative devices 53,

the keys 5O of'the adding machine proper are set so as todetermine the amount that is to be registered and recorded upon the operation of the handle 51.

In the'use of'combined typewriting and adding machines in which statements are made out upon the typewriter and the items registered upon the adding machine, mistakes-are frequently made by the operator striking the wrong f'keys of the adding-mabut the operation of 70 arranged to contact with the v employed that nti amounts are entered on the adding chine, with the result that in writing out the total upon the typewriter as shown by the registering wheels, an erroneous statement will be rendered. \Vi'th the above described interlocking mechanism, the chances of such mistakes are reduced to a minimum, for while the operator is not compelled to depress the proper keys to enable the complete operation of the machine, he is compelled to operate keys of the rows in which the ro er keys are located, and knowing that lie as to operate keys of certain rows, the danger of mistake is greatly minimized, if not entirely eliminated.

WVhile the form of device here shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood tln: it not desired to confine the invention to one form of embodiment here disclosed, for it is susceptible of embodiment in various forms,.all coming within the scope of the claims which follow.
